hello @all,

i replaced my old silcon 40 kva with an originally triple parallel galaxy3500 40 kva. two of the parallel systems were defective and so i connected only a main unit and 2 battery extensions. all this via the existing external bypass.

the system works great and everything is fine. except for one:

i always get a PBus error message on channels 1 and 2, that the communication is faulty.

i would have to tell the system that it is no longer installed in parallel, but only alone.

what can I do?
